Preoperative imaging: A Axial T2-weighted magnetic resonance imaging scan of the brain showing a hyperintense mass adjacent to the brain stem. B A coronal T1-weighted contrast-enhanced magnetic resonance imaging scan showing marked contrast enhancement of the mass. C An axial T1-weighted contrast-enhanced magnetic resonance imaging scan showing marked contrast enhancement and the extension of the mass to the foramen of Luschka. Arrows show the well-circumscribed tumor
